GVS Oxygen 5L Oxy-Pure Ultra Silence Oxygen Concentrator, Grey

Very good product with in the price range, delivery was very quick, got the machine on the same day of purchase...before purchasing I had contacted with GVS persons, they were very responsible explained clearly about the product, also instructed how to use it. Machine is running good till date with low noise from the day of purchase. And I appreciate the customer service people , as they are enquiring about their product regularly like how it's running, any issues I'm facing...never heard a company refering back to the customer after purchasing the product , like GVS enterprises did. Thanks to GVS. and I hope this type of services will be continued to the customers.

Comfortable and convenient to carry this outside if necessity. No sound even in night sleeping time Happy to sleep in continuous process. In these coming days in Hyderabad it is necessary for quality of living to get rid of pollution.

Good product. works well. Low noise.

A really useful medical device and works so well. Easy to use.

Excellent product. We’ve been using this oxygen concentrator for 1 year and it works reliably with consistent oxygen flow. Very satisfied with the performance.

My father did not receive oxygen from this machine and because of this my father passed away today doctor told me to despite proper installation and usage as per the instructions the machine failed to supply oxygen. This is an extremely serious matter involving product failure at a critical time. I have another machine last 4 years but that machine work properly i also request a refund of the product.

very good product

Just go for it , best product ever on market at best price and service. I bought this product for my father,writing this review on last 1 1/2 year perfomance. Perfomance is Very Good and no change in perfomance after long time span also. Noice is very very less,no distrubence to sleep,i seen other product they are very noicy. No troubles till know, have seem some other brands if runing continews trobules start.but this product ran over day and night when my father in emergency and no any trobles after long time service. Operating is very easy, any one can follow those simple instructions to use it or cleaning filters for maintenance time to time.(only external/internal filters need to clean) which is very easy. Spareparts compare to other products resonable and generally replacing things after long run are filter which are less in cost. Other parts give very long service, it is prefered to use Stabilizer to avoid damage by any heavy voltage fluctuioan. Price is best Overall compare to any named brand in market with all benifits and perfonance along good and instant service. I want to mention this, it was emergency when i taken it for my father, dr prefered continews 3 Lt Oxigen. after several products verifying , GVS brand found good, not only in price but best in other features and perfomance, i just thrust on GVS. very soon realised my desition was right at that time. I requested there service to deliver asap as its emergency, they responded emidiatly and delivered. Hats off to all for such helping nature and excelent suport form product/management/customercare staff espially for considering my emergency request for quick delivery for my father. your best service and great product both helped us lot, thanks for all , it proved our thrust is on you alwasy correct. Thank You :-)
